TileDB Vector Search

TileDB Vector Search is a scalable open-source vector database that stores and performs approximate nearest neighbor searches on high-dimensional dense and sparse vectors using TileDB's multi-dimensional array storage for petabyte-scale data. Key features include Vamana graph and IVF-PQ indexing, metadata filtering, multi-tenancy, serverless scalability on object stores like S3, and APIs in Python/C++ with gRPC support. Suited for RAG pipelines, recommendation systems, and anomaly detection; excels in sparse vector efficiency and cost savings compared to Milvus or Pinecone, while scaling better than Faiss for large production deployments.
